Alex Bennée f6698f2b03 tools/virtiofsd: add support for --socket-group
If you like running QEMU as a normal user (very common for TCG runs)
but you have to run virtiofsd as a root user you run into connection
problems. Adding support for an optional --socket-group allows the
users to keep using the command line.
